A uranium nucleus (mass 238 u), initially at rest, undergoes a radioactive decay. After an alpha particle ( mass 4.0 u) is emitted, the remaining nucleus is thorium (mass 234 u). If the alpha particle is moving at 0.050 times the speed of light, what is the recoil speed of the thorium nucleus?
An isotope emits an electron and an anti-neutrino during radioactive decay. The 11. electron moves east with a momentum of 9.28 x 1028 kg m/s and the anti-neutrino moves north with a momentum of 7.47 x 1027 kg m/s as shown in the diagram below. electron recoiling nucleus a. Determine the momentum of the recoiling nucleus. Determine the angle to the nearest 1/100th degree. 3) Answer If scientists only knew where the electron and recoiling nucleus went, which conservation law...

(Figure 1) shows the decay scheme for 137Cs, which has two possible beta decay modes. The first, labeled β1, is a decay directly to the ground state of 137Ba. The second beta decay (β2) is to an excited state 137Ba∗. This excited state subsequently undergoes gamma decay to the ground state. In beta decay, the maximum possible energy of the emitted beta particle is equal to the difference in energy between the initial and final states of the nucleus. The...
